    • In an information signal recording and reproducing apparatus, reproduced data is equalized by an equalizer and a clock signal synchronized in phase with the reproduced data is generated. An equalizing characteristic of the equalizer is controlled according to a difference in frequency between the clock signal and the reproduced data, and a generating operation for the clock signal is controlled according to a phase difference between the clock signal and the reproduced data. The clock signal thus can be stably generated without being affected by variations of temperature and variations due to aging. The equalizer thus has an adequate equalizing characteristic. The apparatus includes a recording mode and a reproduction mode. In the recording mode, a recording clock signal is generated by a clock signal generating circuit and a digital signal is recorded by using the recording clock signal. In the reproduction mode, a reproducing clock signal which is synchronized in phase with a reproduced digital signal is generated by the clock signal generating circuit and the digital signal is reproduced by using the reproducing clock signal.
    • 在信息信号记录和再现装置中,再生数据由均衡器均衡,产生与再生数据同相同步的时钟信号。 根据时钟信号和再现数据之间的频率差来控制均衡器的均衡特性,并且根据时钟信号和再现数据之间的相位差来控制时钟信号的产生操作。 因此,可以稳定地产生时钟信号,而不受温度变化和老化引起的变化的影响。 因此,均衡器具有足够的均衡特性。 该装置包括记录模式和再现模式。 在记录模式中,通过时钟信号发生电路产生记录时钟信号,并通过使用记录时钟信号记录数字信号。 在再现模式中,通过时钟信号产生电路产生与再现的数字信号同步的再现时钟信号,并且通过使用再现时钟信号再现数字信号。
